SemanticVersion

On this page

A software version: 1.2.3-alpha.1+build.5.

Use it for your own or a package's release number. < compares two the way versions are meant to compare. For a range such as ^1.2, use VersionRange.

Shape

Field Type Required?
major Int Yes
minor Int Yes
patch Int Yes
pre_release Text No
build Text No

Write every field when you build one, and give a field that isn't required as none.

Example

example
SemanticVersion { major: 1 minor: 2 patch: 3 pre_release: none build: none }

text.parse(raw, as: SemanticVersion) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as v1.0.0, 1.0 or 1.0.0.0.

Good to know

  • text.parse reads 1.2.3. A v at the front and 1.0 are refused, so give all three numbers.
  • Build metadata, the part after +, is ignored when ordering.
  • == tells you whether two are the same, and < and list.sort_by compare and sort them.

In JSON

A string, in a request, a response or json.write:

json
"1.0.0-alpha""1.0.0-alpha.1""1.0.0-alpha.beta"

When you read one, a field that isn't required may be left out, or sent as null.

Details

Text form, storage, how it is shown, and operations

SemanticVersion is in the group Software, and has been in Jadpo since 0.1.0.

Text form

text.from writes one standard text form, the same form text.parse reads back: 1.0.0-alpha, 1.0.0-alpha.1 and 1.0.0-alpha.beta.

How it is stored

It is stored in 5 columns, each named for the field, _ and its suffix. This is 1.0.0-beta.11:

Column Type Holds
<field>_major bigint 1
<field>_minor bigint 0
<field>_patch bigint 0
<field>_pre_release text 'beta.11'
<field>_build text NULL::text

How it is shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Value Shown
1.0.0-alpha 1.0.0-alpha
1.0.0-alpha.1 1.0.0-alpha.1
1.0.0-alpha.beta 1.0.0-alpha.beta
1.0.0-beta 1.0.0-beta
1.0.0-beta.2 1.0.0-beta.2
1.0.0-beta.11 1.0.0-beta.11
1.0.0-rc.1 1.0.0-rc.1
1.0.0 1.0.0
1.9.0 1.9.0
1.10.0+build.5 1.10.0+build.5
2.0.0 2.0.0

Operations

  • semver.satisfies(version: SemanticVersion, range: VersionRange) -> Bool: Whether version is inside range, as node-semver reads the range: in one of its sets joined by ||, meeting each comparison of it. A pre-release is inside only where a comparison of that set names a pre-release of the same major, minor and patch, so ^1.2.3 never takes 2.0.0-beta.1.

It also takes text.parse, text.from, text.format, json.read, json.write and ==. How every standard type behaves says how they work.
